Calculation Methods of Surrounding Rock Pressure for Small Clear Spacing Shallow unsymmetrically Loading Tunnel

摘要：

　　In the process of construction,it is essential to determine the surrounding rock pressure,which needs to propose the simulation model according to relevant theory,and calculate and analyze the surrounding rock stress,to guarantee the safety of the tunnel construction and operation.However,this has been no perfect calculation theory and formula for surrounding rock stress to unsymmetrically loading tunnel (ULT).The constructed method of failure modes on the shallow ULT are proposed,together with the failure mode for the shallow unsymmetrically load single tunnel,based on the basic assumptions and basic theories of limit analysis method (LAM).
